# Differential reproduction (manuscript revision 2026-09-12): `cull: true` re-founds the lowest-scoring
# lineage from the highest-scoring one after every generation's measurement (truncation selection at
# fixed N = 3; the slot keeps its curriculum order). Latin square as in v5. Arms: isolated + cull
# (selection without recombination) and declinable society + cull (selection with recombination),
# read against the existing isolated and veto arms. Prediction (Discussion): recombination's early
# lead becomes a level advantage; parity again is the null. Seeds via hpc/llm_cull.pbs.
